近年来,用非熔化方法重新利用切屑的可能性正在增长。生产工程研究协会(PERA)为达到同样的最终效果而采用了两种不同的试验方法。第一种方法是把钻削或铣削切屑直接压实成块或预成形坯,然后通过热锻或热挤压进一步强化。PERA的这项研究指出,虽然这种方法简单,但有一定缺点: 由于处理原始切屑困难,因此压实也就困 In recent years, the possibility of reusing chips with non-melting methods is growing. The Production Engineering Research Association (PERA) used two different test methods to achieve the same end result. The first method is to drill or milled chips directly into blocks or preforms and then further strengthened by hot forging or hot extrusion. PERA’s study states that while this method is simple, it has certain disadvantages: compaction is also difficult due to the difficulty of handling the original chips
